HeyJapan is a beginner-to-intermediate Japanese learning application for iOS and Android developed by Language Skills Studio. It structures its curriculum around the Minna no Nihongo textbook series and covers hiragana, katakana, vocabulary, and JLPT N5–N3 exercises for a claimed user base of 7 million learners worldwide.
In-Depth Explanation
Platform: iOS and Android (Google Play: `com.eup.heyjapan`). 5,000,000+ downloads on Android; 4.6 stars with over 230,000 ratings. Free with in-app purchases. Developed by Language Skills Studio, the same team behind Migii JLPT and Todaii.
HeyJapan’s content is structured along the Minna no Nihongo curriculum — one of the most widely used Japanese textbook series in classroom instruction worldwide — making it a useful companion for learners enrolled in formal courses using that series, as well as for self-study learners who want a recognizable pedagogical framework.
Writing Systems
Hiragana and katakana are introduced in dedicated early lessons with stroke order, reading recognition, and writing practice. Lessons progressively integrate kanji as learners advance through N5–N3 content.
Vocabulary and Exercises
The app covers 1,000+ words at beginner levels, organized by topic and JLPT level. Exercises include multiple-choice recognition drills, listening comprehension, fill-in-the-blank grammar practice, and spaced repetition review. Leaderboards and badge systems provide gamification incentives.
JLPT Coverage
HeyJapan covers vocabulary and grammar structures through JLPT N5–N3. It is most comprehensive at N5 and N4 and is not designed as a standalone resource for N2 or N1 preparation.
History
HeyJapan is published by Language Skills Studio, a developer that has built a cluster of complementary Japanese-learning applications including Migii JLPT (for exam preparation) and Todaii (for graded news reading). HeyJapan reached 5 million or more downloads on Android — among the higher download counts for a dedicated Japanese-learning application — and by the developer’s own count has accumulated 7 million total users across platforms.
Common Misconceptions
“HeyJapan covers all JLPT levels.”
HeyJapan is designed for beginners through lower-intermediate learners and covers N5–N3. It is not designed for N2 or N1 preparation; learners targeting those levels should supplement with dedicated test-prep resources such as Migii JLPT.
“The Minna no Nihongo alignment means it replaces the textbook.”
HeyJapan is inspired by the Minna no Nihongo curriculum’s structure and vocabulary sequencing but is a standalone app — not an official companion to the textbook. Learners using both may find vocabulary sequencing familiar, but the app does not replicate or replace the textbook’s full grammar and reading content.
Social Media Sentiment
HeyJapan appears in r/LearnJapanese discussions primarily as an entry-level recommendation for learners seeking structured app-based study. The Minna no Nihongo curriculum alignment earns positive mentions from learners in formal courses. The download count — 5 million on Android alone — is frequently cited as evidence of its mainstream reach. Some advanced learners note it does not extend beyond intermediate level. No significant critical controversy is associated with the app.
